---------------------------+-----------------------------
This is to allow for 'textbook style' of derivatives - something like
\partial!^!{2}/\partial xy\,f(x, y), instead of D[0,1](f)(x,y) for a more
readable output, especially in LaTeX in the notebook environment. I
imagine it working like this:
{{{
sage: var('x y z'); f = function('f', x, y, z)
sage: from sage.symbolic.pynac import textbook_style_deriv
sage: textbook_style_deriv(True)
sage: f.diff(x,z,y,z)
D^4/Dxyzz f(x, y, z)
sage: latex(f.diff(x,z,y,z))
\frac{\partial^4}{\partial\,xyzz}f(x, y, z)
sage: textbook_style_deriv(False)
sage: f.diff(x,z,y,z)
D[0, 1, 2, 2](f)(x, y, z)
}}}
